I took these in my back yard this morning, 5-24-16, in Billings, MT, USA. I just don't see the Red-eyed Vireo bill or head shape, but the eye seems brownish red. The gray legs looks like a vireo instead of a Tennessee Warbler, which Sibley's show as a dark brown or black color. Warbling Vireo looks better for the bill and head, but the eye color is throwing me. Did not sing. Not the best photos, sorry.
Thanks!
